2018/11/17: The American investigations into foreign interference in Trump’s election, and British probes into Brexit, have increasingly become interwoven.

The possibility that both Brexit and the Trump campaign simultaneously relied upon the same social-media company and its transgressive tactics, as well as some of the same advisers, to further far-right nationalist campaigns, set off alarm bells on both sides of the Atlantic.

Damian Collins, a member of Parliament, and chair of its Digital, Culture, Media and Sport Committee, which held an inquiry into fake news, told the Observer, which has broken much of the news about Cambridge Analytica in the U.K., that the new e-mails “suggest that the role of Bannon and Mercer is far deeper and more complex than we realised.

There’s a big question about whether Mercer’s money was used in the Brexit campaign and it absolutely underscores why Britain needs a proper Mueller-style investigation. There are direct links between the political movements behind Brexit and Trump. We’ve got to recognise the bigger picture here. This is being coordinated across national borders by very wealthy people in a way we haven’t seen before."
